How so many have written, the handling is a bit strange. But once you get the hang of it, it's a great thing. I must say that I have fine hairs that respond quickly offended to mechanical and thermal stimuli. What bothered me from the beginning was the first incredible noise, the causes of this part. I have to get up early in the morning and I have not at all manmchmal married, by 5 clock to make the hair dryer, because I would have woken the whole house ... The worst, however, was that it seemed to me the very hot hairdryer. Sure, there are the "cold air" function. But since the brush does not rotate nunmal. That's why I've now bought separately a rotating hot air brush. I can also my hairdryer + round brush rauskramen again ... Well, I thought "Stand at times not so, that should already be so." After all, BaByliss is also no scrap brand.
But the upshot is: I have the warm air brush back now after my hairdresser has beaten his hands above his head at the last visit and had to do damage control. Many Häärchen are canceled, the hair quality was so bad as long gone and my hair flying as with any other brush / hair dryer in advance, which is clearly attributable to the hot hot air brush. Just because I have sensitive hair, I take care of my hair well and regularly. Now I can start all over again, because the hair is so attacked.
For others, the brush may be a great blessing - my personal experience was unfortunately another.
